HBO has announced premiere dates for the highly anticipated new season of "Game of Thrones," as well as "Veep," "Vice" and "Office Space" director Mike Judge's new comedy "Silicon Valley." The network also announced that the upcoming fifth season of "Boardwalk Empire," which will kick off in the fall, will be the Prohibition drama's last.

The fourth season of "Game of Thrones" will launch on Sunday, April 6 at 9pm, with Peter Dinklage, Lena Headey, Emilia Clarke, Nikolaj Coster-Waldau, Kit Harington, Natalie Dormer, Maisie Williams and Sophie Turner all returning to the sprawling fantasy series based on George R. R. Martin's series of novels.

"Veep" will also premiere on April 6th, immediately following "Game of Thrones" at 10pm, with what will be the third season of the political comedy starring Julia Louis-Dreyfus and created by Armando Iannucci.

"Silicon Valley" will have its series premiere on April 6th following "Veep" (and making for an interesting night of very heavy and then very light programming). Created by "Office Space" director Mike Judge, the comedy is set in the Bay Area tech world and has a cast that includes Thomas Middleditch, TJ Miller, Zach Woods, Kumail Nanjiani, Martin Starr, Josh Brener, Christopher Evan Welch and Amanda Crew.

News magazine show "Vice" will be back for a second season on Friday, March 14 at 11pm -- the weekly series is executive produced by Bill Maher, Shane Smith and Eddy Moretti, with CNN’s Fareed Zakaria serving as consultant.

There's no premiere date for the fifth season of "Boardwalk Empire" yet beyond fall, but HBO has determined that the season will be the period drama's last. "We're thrilled to get the go-ahead for a fifth season of 'Boardwalk Empire,'" said showrunner Terence Winter. "After much discussion with my creative team and HBO, we've decided to wrap up the series after such a great run and look forward to bringing it to a powerful and exciting conclusion." The 1920s-set drama is executive produced by Martin Scorsese and stars Steve Buscemi as Atlantic City boss Nucky Thompson.
